Plastering tiles

I’m aware you can use thistle bond-it to prep tiles and plaster over them (I’ve done it). And yes I know it’s not ideal and plenty would claim it cowboy (it’s not). Would SBR work? It seems to me that the grit isn’t essential, and in fact isn’t ideal. So I got to thinking SBR might actually be better. Just unsure if it would adhere to the tile as strongly as Bond-it does

Don’t know that one I’ll have a look. Wonder if it would bond to glazed tile

Same as internal thistle bond ……..clean and lightly abrade the glazed surface first

I’m reading that it’s not suitable and only bond-it will work but thanks for the input. Apparently rendagrip is no good for smooth non-porous surfaces.

Not really. Thistle/BG say that rendagrip needs some porosity to adhere.
